Following a Twitter apology for his recent disses, Sheen fired back at his CBS comedy replacement Kutcher a mere two hours later on the social media site.

Sheen previously extended an olive branch to Kutcher — who addressed the beef on Wednesday’s “Jimmy Kimmel Live” — in 140-characters: “Ashton message received. so sorry u sounded like me! well done! my bad I was pissed at other crap & took it out on you. hope u r good xox c,” Sheen wrote.

Two hours later, he added: “but news flash Dood, you ever tell me to shut the F*** up, EVER again, and I’ll put you on a hospital food diet for a year. c #YaFeelMe Jr?”

Here’s the backstory: Following his highly publicized exodus from the Chuck Lorre sitcom, Sheen has not been particularly kind to anyone on his former show — except for Jon Cryer, most of the time. His latest and largest target has been Kutcher, the man who took over the lead spot on the long-running multi-cam show.

Kutcher finally had enough, and addressed Sheen on Kimmel’s show Wednesday night. Looking directly into the camera, Kutcher offered the following advice to his predecessor: “Shut the f-ck up.”

He added: “Seriously. Like, enough already. It’s like three years later and you’re still blowing me up on Twitter. C’mon, dude. Really?”

That plea seemed to work, for a few hours at least. Here are Sheen’s tweets:
